A stingray whose 'virgin' pregnancy made global headlines has a rare reproductive disease, the aquarium housing her has said. In an update on the health of Charlotte the stingray, the Aquarium and Shark Lab in North Carolina said she had 'developed a rare reproductive disease that has negatively impacted her reproductive system'.
Thousands of people shared their theories on how the pregnancy had happened, with some saying she had been impregnated by a male shark living in the tank. Experts dismissed this, however. 'The morphology of the male shark won't necessarily fit with the morphology of the female round stingray,' Benjamin Perlman, from the biological sciences department at California State University, Long Beach, told NBC's Today.
